Fine, I will be more specific.

"Avalve" is a cylindrical lateral surface area calculation. The X variable is the height of said cylinder, and thus represents the distance the valve is required to move. Keep in mind that lateral surface area is the surface area of an object, minus the top and bottom.

The overall calculation states basic logic. The lateral area uncovered by the valve must equal the area of the barrel opening for full flow.

People should not be afraid of their governments. Governments should be afraid of their people.
